Description
distortion of the input current
waveform (THDi) is poor, but
the system is stable. Weak input
adaptability is suitable for mains
and AC input sources.
Description
If this parameter is set to Enable,
the output current and output
load ratio are displayed as 0 in
the case of no load. If this
parameter is set to Disable, the
output current and output load
ratio are not displayed as 0 in the
case of no load.
If this parameter is set to Enable,
the current at no load will be
calibrated once automatically.
This function can be used only
when the UPS carries no load.
The interruption for the UPS to
transfer from normal mode to
bypass mode is 1–2 ms, and from
bypass mode to normal mode is
0–20 ms. Set this parameter
based on the output interruption
time acceptable to loads.
Cross currents occur during the
transfer between bypass mode
and normal mode, which impacts
the system. This parameter
specifies the number of transfers
between bypass mode and
normal mode within 1 hour,
which ensures system security.
Monitors the current differences
between racks or modules. If this
parameter is set to Enable, the
Mod. Cur. Eql. Data can be
viewed on the running
information screen.
Specifies whether an Inverter
asynchronous alarm can be
displayed on the LCD when the
inverter cannot track the bypass
